Micro Abstract:
To develop and scale degradable bone implants, it is necessary to know the change in mechanical properties of the implant during the degradation process. In this study magnesium sponge structures are being investigated. It is assumed that the magnesium degradation is governed by diffusion of magnesium ions from the surface. To simulate the degradation a numerical model including the diffusion equation was developed. The model was implemented in the commercial finite element code Abaqus/Standard.
